Older fridges can't keep up with the heat — 3 things to consider before buying a replacement

(Image credit: Shutterstock) There's no denying it, we're having a heatwave heavy summer in the U.K. But, while we're all struggling to keep cool, there's something else we need to worry about in this heat — our fridges.I do my weekly online shop at Tesco, but I recently noticed I wasn't able to get some items because the fridges weren't working. And I'm sure I'm not the only one that's noticed the melting chocolate bars on the shelves. So, if the supermarkets aren't coping, how are our fridges going to keep up at home?Well, if you've got an older fridge, it might be bad news. According to Dr Alan Foster, a refrigeration expert who spoke with the BBC, a lot of appliances were: "designed decades ago in a much cooler world."Most were manufactured to cope with temperatures of up to 32C, and with temperatures rising, they're struggling to function. Some owners may even find their fridges stop working entirely.If the current weather has got you considering a replacement fridge, here are the three things you should consider, according to an expert.3 things to consider when buying a new fridge (Image credit: Shutterstock)Buying a new fridge can be a pretty overwhelming purchase. There are so many to choose from and what works for your household might not work for someone else's. Fortunately, we spoke to Ilaria Castagnoli, Product Trainer at SMEG USA to find out her top tips for buying a replacement.1. Check the energy efficiency (Image credit: Shutterstock)Unsurprisingly, if you're buying a replacement because your fridge can't handle the heat, you'll want to prioritise whether a newer model is Energy Star rated. Castagnoli says: "These units will be the most energy efficient options on the market, not only decreasing your energy use but also helping you save on your utility bill in the long run."Get instant access to breaking news, the hottest reviews, great deals and helpful tips.2. Look at different configurations (Image credit: Shutterstock)A fridge isn't one-size-fits-all and if you're combining it with a freezer, you've really got to think about what works for you and the other people in your household. "It's also important to think about the type of food you buy and the layout of the unit that will be easiest for you to manage on a daily basis," Castagnoli advises.This means taking into consideration whether a bottom or top freezer works best for you, whether you'd prefer a side-by-side unit for easier access, or as Castagnoli also recommends: "Families who like to include ice in every beverage, or access filtered water regularly, should opt for a side-by-side or bottom freezer French door configuration." It all comes down to personal preference and needs."It's also important to think about the type of food you buy and the layout of the unit that will be easiest for you to manage on a daily basis."Ilaria Castagnoli, Product Trainer at SMEG USA3. Prioritise features for food freshness (Image credit: Shutterstock)If you're replacing an older fridge, chances are it hasn't got the features that are available on today's market, which are abundant especially when it comes to food freshness.Castagnoli recommends: "Crisper drawers that offer independent temperature and humidity controls are an important consideration because fruits and vegetables often require higher humidity than the main cavity of the refrigerator provides, and different types of produce require different levels of humidity."Additional features Castagnoli suggests looking out aside from food freshness include LEG lighting, adjustable shelving, and even whether a model offers a holiday mode.
